Unknown does not mean incompatible
A Windows-only requirements block does not establish whether a game works through a compatibility layer. Equally, a video of an older playtest cannot establish current performance or reliable controls.
What a useful test should include
Record the game build, SteamOS version, compatibility settings, resolution, graphics preset, input behaviour and stability over a representative session. Note whether the device can complete the normal joining and saving flows.
Before making a purchase decision
Check the current Steam compatibility information and recent build-specific reports. This page will stay unverified until reliable evidence supports a more definite answer.
